> Key: MAPREDUCE-6480

> Project: Hadoop Map/Reduce
> Issue Type: Bug

> MAPREDUCE-6415 added a tool to archive aggregated logs into HAR files. It
> seeds the initial list of applications to process based on apps which have
> finished aggregated, according to the RM. However, the RM doesn't remember
> completed applications forever (e.g. failover), so it's possible for the tool
> to miss applications if they're no longer in the RM.
> Instead, we should do the following:
> # Seed the initial list of apps based on the aggregated log directories
> # Make the RM not consider applications "complete" until their log
> aggregation has reached a terminal state (i.e. DISABLED, SUCCEEDED, FAILED,
> TIME_OUT).
> #2 will allow #1 to assume that any apps not found in the RM are done
> aggregating. #1 on it's own should cover most cases though
